Abstract: X17.00009 : Retarding Damages/Cracks via Auxetic effects and Snap-through Instability
9:36 AM–9:48 AM
Different from the prevalent foam-like cellular/porous materials with auxeticity and/or snap-through-instability-induced negative stiffness. The new composites have no pores/voids and are designed to be relatively stiff and therefore can be used as major protective components in resisting indentation/impact loads. In order to further evaluate the mechanical performance of the new designs, numerical simulations are performed to quantify the relationships between structure, material combination and the effective properties of the new designs.
